The table shows some properties of four elements, P, Q, R and S. Solid P reacts with dilute hydrochloric acid and produces hydrogen. Solid Q does not conduct electricity. Solid R is used to make saucepans since it is a good conductor of heat. Solid S combines with oxygen to form a compound in which atoms of S share electrons with atoms of oxygen. Which elements are metals?
- AP and R
- BP and S
- CQ and R
